CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of application Ser. No. 16/389,626,filed on Apr. 19, 2019, now U.S. Pat. No. 11,126,393, which claims thebenefit of Provisional Application No. 62/660,715, filed on Apr. 20,2018, and the foregoing applications are incorporated by referenceherein in their entirety.

BACKGROUND

It is known in the art to provide greeting cards that are able togenerate sound and/or pop up so-called 3 dimensional images. Typicallythe sound is generated by a small battery and computer chip that isembedded in the card that will produce sound and have an electricalconnection when the card is opened by the recipient. New technology hasevolved to the point where it can be used to improve upon the experienceof the prior art sound and 3 dimensional popup cards.

Also known in the art is the use of conventional small note pads thatare usually provided in a stack of removable, single sheets that alsoare provided with an adhesive substance along a portion of the backsideof each sheet so that they may be written upon and attached to varioussurfaces and removed thereafter. A common example of these is Post-Itnotes. The principles described herein utilize thin screen technologythat is incorporated into an electronic version of prior art note pads.In a preferred embodiment, the thin screen is incorporated into a modulethat mimics the physical dimensions of the prior art pads. The modulecan be provided with any number of attachment mechanisms on the backsideso that it may be attached to a particular surface; e.g., the module mayhave a magnetic attachment means to position it on a refrigerator orother metallic surface, or it could be provided with a commerciallyavailable adhesive that is easily removable, such as those provided byThe 3M Company, to attach it to other surfaces. The module with theincorporated front side screen is equipped with appropriate and wellknown microchips to allow the module to communicate over a network viacommunications standards such as WiFi and Bluetooth. Once connected, theuser would use a website and/or mobile application to enter messages tobe displayed on the screen, and other variables related to the messages,such as time and date, length, disposable, recurring, or link to otherapps, such as an e-calendar. The messages would be saved on the moduleand the website/app. The reader of the messages at the site of themodule could scroll through historic and saved messages through a smallGUI on the screen, which is preferably touch screen enabled.

The principles described herein recognize that technology has nowevolved to the point where video can now be displayed on screens or filmthat are thin enough such that they can be used in the manufacture ofgreeting cards. For example, thin and flexible OLED displays areavailable from companies such as Sony and LG. Other companies aredeveloping their own versions of such screens using LED technology forcertain applications, such as Apple's development of MicroLEDtechnology. Although not yet commercially available, the principlesdescribed herein utilize such screen technology in several new productsand services.

SUMMARY

In one example, a thin film video display is mounted onto card stock andincorporated into a greeting card and is powered by a small power sourcesuch as a conventional dime sized battery and activated when therecipient or other user unfolds the card. The activation mechanism ischosen from mechanisms known in the art, such as mechanisms typicallyused in prior art cards that produce sound effects.

In some embodiments, the card is supplied with prerecorded video and/ormessages appropriate for the intended use of the card. For example, abirthday card could include a prerecorded message of a famous figuresinging happy birthday, and a holiday card could include a snowfall orsummer ocean scenes. If used in other media, the principles disclosedherein could be utilized for consumer information. For example, thetechnology can be incorporated into a menu to show highlights or photosor specials. It could be used in a promotional brochure or marketingpackage, such as those used by agencies and firms looking to attractemployees or investors, to show a small video of appropriate promotionalmaterial in the brochure. The images that could be recorded anddisplayed are limitless.
